K/WUAMI +18 and 49, the result being that as a block of wood is pushed against the splitting elcinent it will lirst receive a vertical split and then a horizontalsplit. By having the horizontal wedges to the rearof the vertical wedges, the result is that the entire splitting does not take place at one time and conse quently a better distribution of power may be secured.

In order to feed appropriate lengths of wood to the splitting device as just desci red, I provide a table 51, which table is movable in the direction indicated by the arrow adjacent thereto. This table is supported upon. asuitable frame work 52 which also provides support for a shaft 03, upon one end of which is mounteda circular saw This saw is adapted to be in line with one edge of the table 51 a's'best shown 111 Figure 2 and is in turn driven through the medium of a bevel gear 56 which meshes with a gear 57 mounted upon'a shaft 58. Power for ro tating the shaft 58 is secured through the medium of gears 59, and 61 and a chain 62 connected thereto, which extends to and around a sprocket mounted upon the shaft 22, Thecourse of this chain is best shown in dotted lines in Figure 1 where it will be noted that the same passes beneath an idler 63. A balance wheel (54 is mounted upon the shaft 58 for obvious reasons.

By now referring to- Figure 5, it will be noted that I have provided a rotatable ruck composed of a series of fingers 66 in parallel alignment as best shown in Figures 1 and 2. These fingers are radially disposed about a shaft 67 journaled upon a suitable support.

It will be noted that this rack is in line with the table 5i so that as a log is laid upon the table 51, the portion to be sawed off will lie upon the rack or fingers (36. In order to prevent retrograde movement of these lingers I provide a latch comprising a pivoted dogGS,

the nose of which is adapted to contact ratchet teeth 69 mounted between two of the fingers and upon the shaft 67. A weight 71 servesto maintain this latch in contact with the ratchet teeth. I At 72 I have shown a grid having fingers 73 extending between the lingers 66 so as to receive the cut oif logs therefrom and to deliver them to the pusheix As this grid is placed. upon a slant, the logs will naturally roll to the lower side and will abut the stop 74 as shown in Figure 6. This step ispivoted as shown at T6 and is provided with fingers 'l'lwhich lingers protrude be tween fingers T8 of the feeding mechanism. This feeding mechanism is pivoted adjacent the side rail $1 of the track 38 and is connected through the :I-HBClll I'I-H of a linl; T9, se-

"cure'd to a cam 31, pivoted as at and adapted to be contacted by a pin 83 mounted upon the pusher i3 7v Tn orderto convey the split material away from the device "I provide a conveyer 8 of the couvcutiiimal type which conveyor is driven by a chain so passin over pulleys at both ends of the conwyer, the power for which is 'liuruishcd by a belt ST as shown in l igure l. The outer extremity of this conveyer may be raised and lowered by a cable 01'? passing over a vertical support 88.

The operation of my device is lows 1- A log is placed upon the table moved lengthwise so that a portion overlies the fingers 66. The table 51 is then moved so as to cause the saw 5s to sever a portion thereof. This i'novement of the log will cause the lingers 66 to revolve and as the log is severed, it will then be in a position to fall upon the grid 73 as retrograde movement of the lingers (56 is prevented by the ratchet teeth 69 and dog (38. The severed portion of the log will then move over the grid and come into contact with the stop T l. Assuming that the same power which operates the saw is "ausing the pitmun rod 34 to move forwardly and rearwzu'dly the result will be that as the pusher -57 moves to its furthest position from the splitting element, the pin 83 will contact the can! 81 which will cause the fingers TS to raise and deliver the severed portion of a log lying therein to a point on the tracks between the pusher and. the splitting element. As the rotation of the crank 32 continues, the result will be that the pusher 37 will. advance and force the log against the splitting element 42 with the result that the log will be split and the split portions will fall upon the conveyor St and be conveyed to a point remote from the machine.

lit will thus be seen that I have provided a mechanism wherein the logs will be snwml and split into predetermined lengths and delivered to a distant pile with but one handling.

It is to be understood that the form of my invention herewith shown and described is to be taken a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the suhjoined claims.

Having thus described my invention, T. claim 1. In a device of the character dcsrriluul, the combination with parallel I beams: a saw mounted on one of said I beams a sliding table mounted adjacent said saw. a plumlily of rotatable radially disposed fingers mounted adjacent said saw and adapted to receive material from said table. a grid positioned in line with said fingers and adapted to receive a severed portion of material thercfrom, means for temporarily retaining the severed portion of material during its travel thereoven and a splitting mechanism comas fol- 51 and LMLLQQG prising a pusher and a splitting element in alignment, said splitting mechanism being the combination with a suitable support,

shafts mounted thereon, gears mounted on said shafts and adapted to mesh with one another, means lor' delivering power to said shafts, a crank secured to one of said shafts, a pitman secured to said crank, tracks mounted adjacent one of said supports, a

pusher movably supported on said tracks and secured to said pitman, a removable splittiiig g element mounted in alignment with i said pusher, a grid extending aeross said support from a point adjacent said pusher at a point on the opposite side of said sup port, a plurality of rotatable fingers adapted to deliver material to said sn 3 aort a slidin V 7 53 table mounted adjacent said fingers, a saw mounted between said fingers and said sliding table :for the purpose of severing a portion oi? material extending from said table to said fingers when said table is moved so as to bring said ntiaterial against said saw.

In testimony whereof I affix my signature.
